Specification of Letters Patent.

- Original application filed January 5, 1912, Serial No. 669,890.Divided and this application filed April 15,

Patented July 28, 1914.

1912 Serial No. 690,736.

To all-whom it may concern:

citizen of the United States of America, and

airesident of New York, county and State of New York, have inventedcertain new and useful Improvements in Compressors, of which thefollowing is a specification, reference being had to the accompanyingdrawings, forming a part thereof.

This invention relates to an improvement plication Serial No. 669,690,filed January 5,

1912. p t e The object of the invention is to simplify and improve theconstruction-and mode of operation, of compressors.

' I will describe my invention in the following specification and pointout the novel features thereof in the appended claims.

In the accompanying drawings: Figure 1 is a sectional elevation of thecompressor connected to a turbine.

Fig. 2 is a horizon tal section taken-on the line 2-32 in Fig. 1. Fig. 3is a fragmentary side elevation of an adjusting mechanism which forms apart of the apparatus.

, As illustrated'in the drawings the coinpressor is operativelyconnected to a turbine, although it is to beunderstood that it may beoperated from any other suitable source of power. The turbine itself isfully described and claimed in my application above identified. It ,maybe briefly de- 'scribed'as follows: It comprises a stationary casing 10having a cylindrical chamber 1.2

;spectively of the casing, said rotor being provided with blades orreaction surfaces 20 between which the motive fluid is introduced. Aseries of impeller blades 253 are mounted upon the shaft 16, and theserotate within the water contained in the casing it; at the shaft16through which flows and is discharged from ports 23 into a chamber24:- This chamber communicates with the spaces between the blades 20 bymeans of ports 26- 27. An exhaust passage 28 is provided which is incommunication with the cylinder 12, and a radiating coil 30 may also beprovided, which communicates at its lower end with the bottom of thecasing 10, and at its upper end with thebottom ,otHthe cylinder 12, thecoil being provided with the usual cooling ribs or fins 31. l

The compressor comprises a cylinder 40 within which a piston 41 isslidable, said piston being mounted on a shaft 42 so that the latter isrotatable with respect to the former. The cylinderAO is provided with aninlet port 44 controlled by a springpressed valve 4:5, and with adischarge port 4.6 controlled by aspring-pressed valve 47. The inletport 44: communicates with a pipe 48 through which air or other fluidsmay be drawn, and the discharge port 46 is connected bya pipe 50 with areceiver 51.

The horizontal shaft 42 is journaled in suitable bearings on the endwalls of the casing 10, and passes through guides 56 which projectinwardly from the casing 10. These guides hold a worm wheel 58 againstendwise movement on the shaft 42 which, as will presently appear, isarranged to move longitudinally, the worm wheel be ing loosely splinedupon said shaft and meshing with a worm 60 fast on the vertical shaft16. Mounted on they end of the shaft 42, opposite to the end upon whichthe piston 4H. mounted, is a propeller 62. This propettcr driven by theengine and the end thrust it produces on the shaft, is utilized toactuate the compressor, but it should-be understood that other meansforproducing aslot- 73 which is substantially parallel with l the shaft4-9,

The arm 70 is provided with a pair of, lugs M415 which straddle theshaft 42 the path of travel of the worm 64, A spring 7 6 normally holdsthe arm 70 f9 and thus vary the and the fulcrum 72.

provided v iitli areduced' end 80 which is slidable in a lug 82projecting upward from so arranged. thatits position. may be manu allychanged by means of a finger 84 on ashaft 85,- said finger engaging pins86 on said bar. A hand wheel 88 is provided on the shaft 85 outside ofthe casing 10, whereby the shaft may be rotated to adjust-the'barposition of the lug 7 8 The hand'wheel 88 is provided We peripheralnotches; 89 adapted to receive a locking finger 90 projecting from theside "of the easing-10, whereby the hand Wheel mayzbe lockedagainstrotation. The lever 70, as will-be'pointed out, 1s provided tocoact with other parts of the mechanism for the purpose of causing areciprocatory movement of the shaft 4:2, and this ad ustment of the arm79 will vary the length orstroke of this reciprocatory movement.

When the shaft 16 is rotated, the worm 66'meshing with the worm wheel 58causes the propeller shaft llto rotate. The star Wheel 69 being inengagement with the lever 70 is prevented from rotating. and'with 1ttheworm wheel'65 on the-shaft 66 'is held stationary. The I rotation ofthe propeller shaft 42 and the engagement of the worm .464; with thewheel 65 causes the propeller shaft to bemoved longitudinally toward theright, thus moving piston 41' to the right and drawinga charge of fluidinto-cylinder of the wot-m6 Thiscauses" the arm 7 6 to disen age "thestar wheel 69, whereupon the end t must of the propeller causes theshaft fdflto be pushed back'toward the left thereby'rotating the gear165'and forcing the pis- -;ton 41 inctheicylinder 40 to compressthe chargemthe. cylinder and force it through the-port 46 and pipe to the receiver51.

While the shaft42 is moving toward the -'-left"the lever Maia-allowed tomove back un'der'- theaction of its spring 76 into the path'ofzimovementof the star-wheel 69 so that as soon as the: next armof the latter Ireaches the end of the lever 70, the rotation :of the r'worm wheel 65will be arrested and the shaftsdQ will move again to the right.

This movement will cause the piston 41 to --draw' a new charge into thecylinder 40 l through the port By the use of this device the compressor,

The combination of a rotary and reciprocatory shaft, gearingarranged to rotate said shaft and cause it to move longitudinally in onedirection, a propeller tending to produce an end thrust in the oppositedirection, means operable by the longitudinal movement of said shaft forreleasing said gearing to allow the shaft to be moved longitudinally inthe opposite direction by the end thrust rotation. whereby when-saidfirst mentioned shaft is rotated it is moved-longitudinally in onedirection, said lever being arranged to be tripped by said firstmentioned shaft to free said second shaft,'whe reby said first mentionedshaft is moved longitudinally in the opposite direction by and thrust.
